Application filed August 2 in the accompanying drawing, Figural-is a vertical section of the'apparatus. Fig.2 is an enlarged vertical section of the cntl'of the shaft. Fig. 3 is an end view of the saine. Fig. 4 is a perspective viewof the hangers. Fig. 5 is "a broken plan view of the apparatus.

' Fig. 6 is a broken vertical section of the same at right angles to Fig. 1. Fig. 7 is an enlarged cross-section of the roller. Fig. 8 is an. enlarged longitudinal section of the same.

Referring to the drawings, 1 represents the outer float, which supports the entire apparatus. Said float is preferably rectangular in form, made of hollow walls made watertight, and is securedin the desired position by cables? and anchors. (Not shown.) Attached to the inner side of opposite Walls of said outer float are vertical boxes 3, the lower ends of which have secured therein.

- and then bent out at right angles to enter recesses 9 in the circumference of the roller and bolted to said' roller by bolts 10. By this means the ends of the deflector are lirrnlysecured to the rollers, which rollers roll in the half-round bearings in the main boxes 3.

merit. Theseboxes 11 serveasguideways for the ends'of a' transverse shaft 15, carry ing the working .flbats: .Each end of, the shaft is slotted or forked, as shown at i6, and in-said slot. is contained afroller 17, a pin 18 being passed centrally through said roller and through the sides of the fork. Said pin 18 also passes diametrically througha collar 19, encircling said forked end.- Said collar thus shields the end of the shaft, and particularly the roller, as it moves up and down in the box 11. Next to the fixed collar 19 on on each end of the shaft is a sleeve 20, which can refvclveupon the shaft, being held in posi titon by a collar .21, fixedly secured on said shaft, the sleeveZO contacting with the sides of the box 11 as the end of the shaft moves up and down. Next to each fixed collar 21 are arranged loose upon'the shaft apair of hangers 22 23 for the twin working floats 24 25.

Said hangers comprise sleeves surrounding the shaft sideby side and depending arms 26 beneath the sleeve of the other hanger. The arms 26 27 of these hangers are secured to the inner sides of the The fixed collars 21 are made sufficiently long to serve as spacing-washers, maintaining the ends of the twin floats out of possible contact with the vertical boxes 3 and 11., notwithstanding the tilting of the shaft due to the. motion of the waves.

Each twin float is in cross-section ,approximately an isosceles right-angled triangle,

the equal sides being in the position of rest,

vertical and horizontal. The outer edge of the horizontal side of each float is attached by ball-and-socket joints 40 to piston-rods 41 of pistons 28, which reciprocate in the cylinders 29 of air-compressors pivoted on trunnions 30, through one of which trunnions the compressed air passes by a pipe 31, having therein a check-valve 32, to a 001D- mon pipe 33, leading to a compressed-air reservoir 34 and also to a compressed-air engine 35, operating a shaft 36 from a pulley 37, on which power is transmitted to an electric dynamo 38, generating electricity. The working floats2425. are suitably weighted at their lower edges, preferably by iron bars 39, secured to their inner sides. The operation of the apparatusis as follows: The deflector being heavily Weighted offers great resistance to the momentum of the waves, so that a Wave striking it. on either side is deflected and .impinges1upon AVAILABLE COPY the lower oblique face of the corresponding .working float. It thereby raises said float and passes under the edge thereof and impinges against the inner vertical side of the other twin float, thus lifting .both floats, and correspondingly operates the pumps. As the wave passes on, said floats drop in the same order, the Weights t the'bottom of the floats brings them down to their original positron, ready for the impact of another Wave.

. A Wave coming from the opposite" side will end of the shaft relative to the otherend; third, rise and fall of the shaft and the work- I ing floats bodily.

, such 'storms'without materially interfer' with the actionof the waves thereon.

Thus the apparatus Works most effectively in transmitting the torce'oi the Waves. i The apparatus comprising the HAP-60111:
